中文百科

过渡金属 Transition metal

(重定向自Transition Metals)

过渡元素英语:Transition element)是指元素周期表中d区的一系列金属元素,又称过渡金属英语:Transition metal)。一般来说,这一区域包括3到12一共十个族的元素,但不包括f区的内过渡元素。

“过渡元素”这一名词首先由门得列夫提出,用于指代8、9、10三族元素。他认为从碱金属到锰族是一个“周期”,铜族到卤素又是一个,那幺夹在两个周期之间的元素就一定有过渡的性质。这个词虽然还在使用,但已失去了原意。

过渡金属元素的一个周期称为一个过渡系,第4、5、6周期的元素分别属于第一、二、三过渡系。

英语百科

Transition metal 过渡金属

(重定向自Transition Metals)

In chemistry, the term transition metal (or transition element) has three possible meanings:

English chemist Charles Bury (1890-1968) first used the word transition in this context in 1921, when he referred to a transition series of elements during the change of an inner layer of electrons (for example n=3 in the 4th row of the periodic table) from a stable group of 8 to one of 18, or from 18 to 32. These elements are now known as the d-block.
